What Causes Incomplete Right Branch Bundle Block
Incomplete RBBB: This is a relatively innocuous condition where the electrical conduction in the right ventricle is not completely normal. It is believed to be due to an abnormality in the electrical conduction fibers. It is not typically associated with any clinically significant cardiac problem. The vast majority of persons with this do absolutely fine and live normal lives. ...Read more
Irbbb usually safe: Irbbb is usually an ECG anomaly that may speak of some right sided enlargement or strain (can occur in atrial septal defect or in pulmonary processes with right heart strain ). It can also occur innocuously and unrelated to cardiac structural changes. It does not typically imply impending conduction system collapse and is not a predictor for cardiac arrest or sudden cardiac death. ...Read moreSee 1 more doctor answer
I was diagnosed with incomplete right brundle branch block & may start lexapro (escitalopram). Concerned that Lexapro (escitalopram) has been shown to cause qt prolongation.
Mild conduction prob: The righty and left ventricles are induced to beat through electrochemical currents transmitted through the right and left bundle branches, respectively. Irbbb means part of the right bundle is not transmitting fully. It is a benign condition of no significant clinical consequence. ...Read more
Not true "block": Two bundles of electrical tissue carry each heartbeat from the top part of the heart to the bottom--the "right" and "left" bundle branches. When one of these doesn't conduct at all, or does so much more slowly than the other, it is a complete bundle branch block. When one conducts slightly slower than the other, it is called "incomplete" bundle block. This often is of no clinical consequence. ...Read moreSee 1 more doctor answer
Depends, of course: Most cases of bundle branch block are due to a focal injury to a key part of the heart's electrical conduction system. Coronary disease, scarring from trauma, infection, or natural processes can cause it. Some illicit drugs, especially those creating coronary spasm (e.g., cocaine, amphetamines) may create those conditions, and frequent exposure (repetitive) only exacerbates the risk. ...Read moreSee 1 more doctor answer
